9. HABENELLA Small.

 base. Stigma with two short appendages, the glands naked. 



1. Habenella Garberi (Porter) Small. Stem 3-6 dm. tall: leaf -blades oblong 

 to oblong-lanceolate, 6-10 cm. long, acute: lateral sepals very broad, 5.5-6.5 mm. 

 long: petals about 4 mm. long, sinuately 3-lobed at the apex: lip 6-10 mm. long, 

 broadly linear, obtuse: spur 12-18' mm. long: capsules spreading, the body 9-13 mm. 

 long, longer than the stipe. 



In hammocks, peninsular Florida. Fall and winter. 



10. GYMNADENIOPSIS Kydb. 



Caulescent herbs. Flowers in a terminal spike. Perianth white, pink, greenish 

 or orange-yellow. Sepals distinct, the lateral ones slightly inequilateral. Petals 

 mostly smaller than the sepals, undulate, sinuate-lobed or erose. Lip entire, 3-lobed 

 at the apex, or crenulate or erose. Anthers with parallel approximate sacs, and naked 

 contiguous glands. Stigma with 2 or 3 appendages at the beak. Summer. 



Lip 3-lobed at the apex: spur clavate. 1. G. clavellata. 



Lip entire or erose-crenulate: spur filiform. 



Lip, and petals, entire; perianth white or pink: spur longer than the ovary. 2. G. nivea.
